Upgrade Mendix 9 app to Mendix 10

Hi everyone,   I am trying to upgrade my Mendix 9.24.6 app to Mendix 10. I've tried using Mendix Studio Pro 10.0.0 and 10.1.1. They both show the App in the list (see below) in the location where I last opened and commited it from using Mendix 9. They all show the app as being unversioned. Which I cannot explain, since it commited just fine in Mendix 9 before. If I open it anyway and commit it, then I get a new App on my Dev Portal which is Free rather than Licenses like the other/original app.   Any ideas what might be going on and how to address it?

Did you migrate the version control from SVN to Git?
